What does funny lady Betty White share with teen singing sensation Justin Bieber?

What do film star Sandra Bullock and hoops star LeBron James have in common?

All are among this year’s crop of “The 10 Most Fascinating People,” as harvested by Barbara Walters from the fields of entertainment, sports and world affairs.

Also on the list: GOP superstar Sarah Palin, incoming “American Idol” judge Jennifer Lopez, royal fiancee Kate Middleton and the entire cast of MTV’s “Jersey Shore.” Two more Most Fascinating People are yet to be disclosed, and, as usual, the 10th name will be kept under wraps until the ABC News special airs Dec. 9 at 10 p.m. EST.

This is the 18th year Walters has presented her roundup of the biggest and most buzzworthy. But this year, there’s more. She’s got a companion special the same night.

An hour earlier – at 9 p.m. EST – Walters is hosting “Oprah, The Next Chapter.” It’s an in-depth visit with Winfrey as she readies OWN, her new cable network launching Jan. 1, and roars down the home stretch of her daytime talk show’s final season.

“I interviewed her in 1988, when she was first becoming very popular,” Walters said not long ago. “She and I consider this latest interview our coming full circle.”

On the program, Winfrey will discuss her new network, the reason she’s doing it and concerns she has for its success – “it’s a huge leap of faith,” Walters said.

Winfrey also talks “very personally” about her relationships with best friend Gayle King and longtime partner Stedman Graham.

“This is an interview about Oprah’s life at this turning point,” Walters said.

That’s gonna be on my DVR!
